Maybe not 3 * 8 hours, but it is still time consuming.
The instructions to do it (as given by the previous release manager) is 3 pages long.

About half a day.

Never used this tool, so I can't say.

All these steps are automated by a script. At each release I update and improve the script (and that also takes time).

In the process of a major release, we create a branch, so the release branch will always be present.

This is exactly the issue of the 2.22 branch: almost stagnant.

I don't want to create many minor releases. And there are major bugs and minor bugs.

Basically, we follow 2). There is a stabilization period of about 1 month.

I am not sure that SCM tool is an issue here.

One more work about binutils release: I think it is not as important as it was in the past. Many (> 99% maybe) of binutils users use Fedora/Suse/RH/XXX versions of binutils, which follow a second release process.
